Other effects, like morphs, motion, and zooms work better (with less ghosting or latent effects) in top-to-bottom orientation, but can be achieved in both directions. 3D effects can be achieved only in a lateral (left-to-right) orientation, as the viewer's left eye must see them from a slightly different angle to the right to achieve the stereoscopic effect. Alternatively, several images of the same object, taken from slightly different angles, can be used to create a lenticular print with a stereoscopic 3D effect. Though normally produced in sheet form by interlacing simple images or colors throughout the artwork, lenticular images can also be created in roll form with 3D effects or multi-color changes. If a sequence of images is used, it can even show a short animation. The combined lenticular print shows two or more images by changing the angle from which the print is viewed.
#LENTICULAR PRINTING PRICES REGISTRATION#
When printing on the backside of the lens, the critical registration of the fine "slices" of interlaced images must be absolutely correct during the lithographic or screen printing process to avoid "ghosting" and poor imagery. The interlaced image may be printed directly on the back (smooth side) of the lens, or on a substrate (ideally a synthetic paper) which is laminated to the lens. Once the images are collected, they are arranged in individual frame files, then digitally combined into a single file in a process called interlacing. It can be used to create frames of animation, for a motion effect offsetting the various layers at different increments, for a 3D effect or simply to show sets of alternative images that appear to transform into each other. Lenticular printing is a multi-step process which consists of creating a lenticular image from at least two images, and placing it behind a lenticular lens.
